uncommon Formation in the Viscera of the Human Body, 6 . 1 
From the curvature of the aorta there first arose the com- 
mon arterial trunk, which, in this subject, divided into the left 
carotid and subclavian arteries ; whilst the right carotid, and 
subclavian, proceeded from the aorta by distinct trunks. 
The inferior aorta gave off the czeliac, which, as usual, di- 
vided into three branches ; however, that artery which was 
distributed to the liver appeared larger than common ; it 
exceeded, by more than one-third, the size of the splenic 
artery of this subject. This was the only vessel which sup- 
plied the liver with blood, for the purpose either of nutrition, 
or secretion. 
The vena portarum was formed in the usual manner, but 
terminated in the inferior cava, nearly on a line with the 
renal veins. The umbilical vein of this subject ended in the 
hepatic vein. 
The liver was of the ordinary size, but had not the usual 
inclination to the right side of the body ; it was situated in the 
middle of the upper part of the abdomen, and nearly an equal 
portion of the gland extended into either hypochondrium. 
The gall bladder lay collapsed in its usual situation ; it was 
of a natural structure, but rather smaller than common ; it 
measured one inch and a half in length, and half an inch in 
breadth. On opening the bladder, we found in it about half 
a tea-spoon full of bile ; in colour it resembled the bile of 
children, being of a deep yellow brown ; it also tasted like 
bile ; it was bitter, but net so acridly or nauseously bitter 
as common bile. 
I diluted a small quantity of this fluid with water, and 
with this liquor moistened some paper which had been 
tinged with a vegetable blue; this was instantly changed.
